The other day I was arguing with my friend about what will happen if we ever come in contact with another alien species like us? The most probable outcome was they will destroy us like we always do to other species. This is logical, they will come to us here on Earth and when they see we are not powerful enough to match them, they are going to dissect us. Even if we can match them there will be a war. So, our destruction is obvious.
But, after watching these images I am sure we do not need an extraterrestrial threat to destroy us. Our own action is killing mother earth and our species. We are taking a lot of other species to the extinction with us.
